Assessment of reclaimed asphalt pavement (RAP) as recycled aggregate for concrete
Graphical abstract Display Omitted
Highlights Reclaimed asphalt pavement (RAP) was tested as aggregate replacement for concrete. Five types of RAP sourced by different Italian collection sites were characterized. RAP shows irregular porous surface due to bitumen covering the natural aggregate. RAP shows hydrophobic behavior. RAP exhibits dimensional stability and frost resistance.
Abstract A study about the performances of reclaimed asphalt pavement (RAP) sourced from 5 different Italian collection sites is presented to evaluate RAP as aggregate for concrete. Several RAP properties were investigated: physical properties (particles size distribution, water absorption, porosity, wettability), microstructure by microscopy, dimensional stability (drying shrinkage of mortar and concrete with 100% of RAP as aggregates) and durability assessment by freezing-thawing cycles. Several differences between RAP and natural aggregates used for concrete were highlighted. The use of RAP as recycled aggregate for concrete is a promising route, but a complete characterization is needed to ensure concrete performance and durability.
